Worked on the ROCm/rocm-systems repository, delivering profiling and observability features for high-performance GPU workloads. Over four months, developed and enhanced tools for GPU process metrics, XGMI and PCIe profiling, and UCX-based communication tracing, focusing on reliability and actionable diagnostics. Used C++ and Python to implement runtime SELinux detection, SDMA usage metrics, and robust error handling, while refining logging and documentation for operator clarity. Improved profiling accuracy and reduced misconfiguration risk by introducing safer defaults and automated testing with CMake and ctest. The work strengthened profiling workflows, streamlined onboarding, and improved system validation across diverse Linux and GPU environments.

Feb 1, 2026February 2026 ROCm/rocm-systems monthly summary focused on boosting observability, profiling reliability, and safe defaults across the ROCm profiling stack. The work delivered concrete metrics enhancements, profiling correctness improvements, and documentation updates that improve developer and operator confidence and reduce risk of misconfiguration. Key achievements and business value: - Implemented GPU Process Metrics: SDMA Usage feature, adding a per-GPU SDMA usage metric with user-friendly formatting and a time-conversion helper. This improves monitoring visibility and enables faster issue detection for SDMA-related performance. (Commits: 79aac4ad5973690605dc84ede7f5577b05330800) - Fixed ROCm Profiling UCX Initialization: Corrected UCX data tracking in the profiler, ensuring Send/Recv bytes are captured reliably. Added rocpd validation tests and optimized UCX availability handling to reduce false negatives in profiling. (Commit: e1381cd1dbac81f2c4cf797b184875afd8bc0cbf) - Disabled UCX Profiling by Default with Documentation: Reduced risk of accidental profiling overhead or misconfiguration by turning off UCX profiling by default; updated docs and logging for clarity and safety. (Commit: 4768e2f6bbf925bccbcf85f1f0543a6e1b31c6d6) - Documentation and How-To Enhancements: Updated documentation for communication-runtime profiling and ROCm profiler usage to reflect default changes and new metrics, improving onboarding and maintenance readiness. (Associated commits in above changes) Overall impact: Improved observability and reliability for GPU process metrics and UCX profiling, safer defaults to prevent unintended profiling overhead, and clearer developer guidance, enabling faster detection of issues and safer deployments for customers. Technologies and skills demonstrated: system profiling integration, metrics instrumentation, UCX/ROCm profiling, C/C++ instrumentation, Python helpers for formatting, test development (ctest/validation), and documentation across the ROCm ecosystem.

Sep 1, 2025Month: 2025-09 | ROCm/rocm-systems delivered a security-consciousGuard and debugging enhancement for HIP workloads. The key change adds runtime detection of SELinux enforcing mode during library initialization and aborts execution with a clear, actionable error message when enforcing is active. It also refines HIP Stream logging verbosity for clearer debugging and faster triage of issues in HIP-based workloads. A new user-facing guidance was added to help operators adjust SELinux settings as needed. Impact: prevents misbehavior and silent failures in enforcing environments, reduces debugging time, and improves security posture for ROCm deployments.
